PORT ST. LUCIE – Matt Harvey is busy forging his comeback from Tommy John surgery, but he is keeping an eye on the Alex Rodriguez saga with the Yankees. He offered words of support to Rodriguez, who apologized to Yankees brass on Tuesday at Yankee Stadium.

“Obviously Alex wants to play, that’s good for him, good for baseball,’’ Harvey told The Post.

“If he is that dedicated and wants to come back then more power to him for going up to the organization like that, it shows a lot. It will be exciting to see what he can do.”

Rodriguez is returning from a season-long drug suspension. Harvey missed the entire 2014 season recovering from elbow reconstruction. He took a significant step forward in his return Tuesday when he threw his first bullpen session at the Mets spring training complex. He came away feeling healthy and strong and participated in Wednesday’s workout.

Harvey is looking forward to competing again in the Subway Series and facing A-Rod and the rest of the Yankees. Harvey grew up a Yankees fan in Connecticut, attending Subway Series games with his dad.

“Those are always fun, and it’s a good feeling to be healthy for that to come,” Harvey said.
